Taking Suffering Out of Science

Together, we can reduce unnecessary animal testing.

Each year, millions of animals endure painful, often unnecessary experiments in the name of research and education. Many of these animals are deliberately sickened over long periods, left to suffer without anesthesia or die without euthanasia. This is despite modern technology that often makes such tests less scientifically accurate and less cost-effective.

As an infant chimpanzee in the wild, Bullet lost his right arm due to a gunshot wound from the same hunter who shot and killed his mother. He then spent years in a research lab as the subject of medical experiments. In 2017, we were able to secure funds for his long-term care.

Rats and mice are the most commonly used animals in research, but many different species fall victim to animal testing. “Class B” dealers try to acquire cats and dogs through animal shelters and “free to a good home” ads to sell to research labs. Live goats and pigs are frequently injured deliberately to train military personnel to respond to combat injuries, even though cruelty-free training alternatives exist.

Animal research by the numbers

25MILLION

VERTEBRATE ANIMALS

Are used annually in research, testing and education in the United States.

80-90%

OF TESTED ANIMALS

Are mice and rats, making them the overwhelming majority of animals used in research. Despite this, these species are neither counted in the annual statistics that the USDA collects, nor covered under the Animal Welfare Act.

200+

CHIMPS

Live at Project Chimps, a sanctuary founded in Georgia in 2014, where these former research subjects have been moved from laboratories into retirement.

Millions of animals are used in experiments each year at universities, hospitals, military bases and companies around the country. Some receive no medication or other relief for their suffering. By donating, you'll help us work toward the day when animals are no longer used in harmful experiments.

The strength to survive

Emma was one of many animals given a second chance this year, thanks to you. Please help us rescue even more just like her.
